nm_device_get_hw_address() may return NULL and nm_platform_link_get_type may
return NM_LINK_TYPE_NONE. While it might be a good idea to check for such cases
at the init time it seems easier to just ignore it and prevent blowing up in
subsequent deactivation.
A quick test case:
# while :; do ip link add moo0 type veth peer moo1; ip link del moo0 ; done
Yields:
NetworkManager:ERROR:devices/nm-device-ethernet.c:268:constructor:

nm_device_set_hw_addr: assertion 'addr != NULL' failed

For IPv4, iproute for example defaults to a metric of 0.
Hence, the name NM_PLATFORM_ROUTE_METRIC_DEFAULT was misleading.
Also add a NM_PLATFORM_ROUTE_METRIC_DEFAULT_IP4 define for completeness.

We recently changed default values for route metrics. Revise that
again and increase the space between the default values.
No strong reason to do this, but it seems better to have larger
gaps and make use of the available range.
For IPv4 addresses, the kernel automatically adds a route when
configuring an IP address. Unfortunately, there is no way to control
this behavior or to set the route metric.
Fix this, by adding our own route and removing the kernel provided
one.
Note that this adds a major change in that we no longer call
nm_ip4_config_commit() for assumed devices.

We've previously been just watching for state changes into UNMANAGED state. No
state change is emitted upon removal of a device which is already unmanaged.
https://bugzilla.gnome.org/show_bug.cgi?id=737659
Before, we would only track a device in NMDefaultRouteManager
if it had a default route. Otherwise the entry for the device
was removed.
That was wrong, because having no entry meant that the interface
is assumed and hence we would not touch the interface. Instead we must
esplicitly track devices without default route to know when an interface
has no default route.

The previous commit made NM enforce the default route on interfaces for
which NM manages a default route.
For interfaces that are configured never-default, NM will now pick up
any externally configured default route, as if it was managed by NM.
This is important, because NMDefaultRouteManager needs a notion of which
is the best device. Without this change, it was agnostic to default routes
on managed, never-default interfaces.

When calling update_default_route(), NMDefaultRouteManager will look at the
source, and determine whether it has a default route or not. For example
for device sources, this means calling nm_device_get_ip4_default_route().
If the source indicates that it has no default route, the effect of
calling update_default_route() is the same as calling
remove_default_route() (hence, remove() can be replaced by update()).
If the source however still indicates a default route, the behavior
would be different. This case would be an undesired inconsistancy,
because source and NMDefaultRouteManager would disagree of whether
the source has a default route.
Source must always properly indicate whether it has a default route
or not, hence this situation does not arise.
Hence it is always better to call update().

Not invoking a callback when cancelling the operation is counter
intuitive.
Note that NMPolicy refs the device, cancelling the call would leave
the reference hanging. That was not an issue because the call was
never cancelled. But still the behavior of NMFirewallManager is
unexpected.

The kernel does not terminate an ongoing IPv6LL address process when
the IPv6LL address generation mode is set to 'none' (indicating that
userspace wishes to handle IPv6LL). Next, NetworkManager does not
expose IPv6 addresses internally until they have completed DAD. This
means that the kernel may still be performing DAD for an IPv6LL
address when NetworkManager turns userspace IPv6LL on, and when
DAD is complete NetworkManager will finally pay attention to the
address. If the device is in the DISCONNECTED state, NetworkManager
will then generate and assume an IPv6LL-only connection on the device.
Unfortunately, that behavior happens if the following is true:
1) IPv6LL addressing takes a while (eg, dad_transmits is high or
the kernel takes a while for some reason)
2) the activated connection fails quickly (dhclient fails or some
other fatal error terminates the activation attempt)
3) the activated connection has ipv6.method=ignore
In this case, when the device was brought up and ipv6.method=ignore,
NetworkManager re-enabled kernel IPv6LL and reset the IPv6 sysctl
properties. The kernel then generated an IPv6LL address and began
DAD. dhclient failed quickly, and NM deactivated the device. NM
then turned off kernel IPv6LL when deactivating the device, but the
kernel does not terminate the ongoing DAD. Some time after the device
entered the DISCONNECTED state, the kernel finished DAD and that
allowed NetworkManager to internally see the address, which caused
NetworkManager to emit the 'recheck-assume' signal. This
generated a new IPv6LL-only connection which was then assumed.
Bouncing 'disable_ipv6' when re-enabling userspace IPv6LL during
device deactivation flushes the tentative kernel IPv6LL address,
thus preventing the address from being announced after userspace
IPv6LL is re-enabled. The other alternative is to expose
tentative addresses (eg those still doing DAD) in NMPlatform so
they would be flushed when the device deactivates, but that is a
larger & riskier set of changes.
Reproducer:
- ifconfig eth0 down
- prepare a DHCPv4 connection with ipv6.method=ignore
- set /proc/sys/net/ipv6/conf/all/dad_transmits to "15"
- ensure that DHCPv4 will fail (replace dhclient with a script
that exits after 2 seconds or something)
- run NetworkManager
- activate the DHCP connection and watch it immediately fail
- wait for the kernel to announce the IPv6LL address after DAD finishes
- watch NM "assume" the new IPv6LL connection
https://bugzilla.gnome.org/show_bug.cgi?id=740096
For ipv6.method=dhcp NM was not waiting for an IPv6LL address, which
caused the DHCP client to exit early because it had no local address
to bind to.

config.h should be included from every .c file, and it should be
included before any other include. Fix that.
(As a side effect of how I did this, this also changes us to
consistently use "config.h" rather than <config.h>. To the extent that
it matters [which is not much], quotes are more correct anyway, since
we're talking about a file in our own build tree, not a system
include.)
It is conditionally compiled depending on presence of bluez-libs.
Results in undefined symbols:
NetworkManager[19346]: <warn> (/libnm-device-plugin-bluetooth.so): failed to
load plugin: /usr/lib64/NetworkManager/libnm-device-plugin-bluetooth.so:
undefined symbol: nm_bluez5_dun_cleanup
When quitting, the Manager asks each device to spawn the interface helper,
which persists and manages dynamic address on the interface after NetworkManager
is gone. If the dynamic address cannot be maintaned, the helper quits and
the interface's address may be removed when their lifetime runs out.
To keep the helper as simple as possible, NetworkManager passes most of the
configuration on the command-line, including some properties of the device's
current state, which are necessary for the helper to maintain DHCP leases
or IPv6 SLAAC addresses.
Really only used by systemd because it doesn't have as good lease
handling, but it's also necessary if we switch DHCP clients mid-stream
(which we'll be doing later) since the new DHCP client won't
have a lease file for the current IP address, and thus has nowhere
to pull the current IP address from to request the same address
from the DHCP server.
We'll ever have WWAN devices with a NULL gateway because the IPv6 over
WWAN still uses router advertisements to get a prefix. Thus you'll
always have a gateway if the device has real IPv6 connectivity.
For the IPv4 case, we still allow default routes without gateway on
WWAN.

Up to now, NMPolicy would iterate over all devices to find the "best"
device and assign the default route to that device.
A better approach is to add a default route to *all* devices that
are never-default=no. The relative priority is choosen according to
the route metrics.
If two devices receive the same metric, we want to prefer the device
that activates first. That way, the default route sticks to the same
device until a better device activates or the device deactivates.
Hence, the order of activation is imporant in this case (as it is
already now).
Also, if several devices have identical metrics, increment their
metrics so that every metric is unique.
This makes the routing deterministic according to what we choose as best
device.
A special case is assumed devices. In this case we cannot adjust the metric
in face of equal metrics.
Add a new singleton class NMDefaultRouteManager that has a list of all
devices and their default routes. The manager will order the devices by
their priority and configure the routes using platform.
Also update the metric for VPN connections. Later we will track VPN
routes also via NMDefaultRouteManager. For now, fix the VPN metric because
otherwise VPNs would always get metric 1024 (which is usually much larger then the
device metrics).

Make use of the new setting nm_setting_ip_config_get_route_metric()
If set, this override the route metric determined based on the device
type.
Similarly for VPN also prefer the setting from the connection. Thereby change
the default priority (for VPN that have their own device) to NM_VPN_ROUTE_METRIC_DEFAULT
instead of NM_PLATFORM_ROUTE_METRIC_DEFAULT. The latter would be a very
low priority compared to the default metrics for devices.

Before, we would always call unanimously nm_device_get_priority()
to get the default route metric for a device. Add new functions
nm_device_get_ip4_route_priority() and nm_device_get_ip6_route_priority()
and use them at the proper places.
Also add new function nm_vpn_connection_get_ip4_route_metric() and
nm_vpn_connection_get_ip6_route_metric().

nm_device_get_priority() is used to select the "best" device
for the default route. The absolute values don't matter
at that point and the relative ordering is not changed by
this patch.
It is also directly used for route priority/metric. As we soon
allow the user to overwrite the setting, we want to get more
space between the individual device-types.
That way, a user could overwrite the default metric for a wifi
device to be 109 (making it lower then the default value 110), but
still less preferred then other non-wifi types.
Obviously, this patch is a visible change of behavior as now
routes get different metrics assigned.

Now that NMSettingIP6Config inherits the dhcp-send-hostname property
from NMSettingIPConfig, fix things up so that it actually gets used.
(Note that this changes behavior: previously if ip6.dhcp-hostname was
unset, no hostname would be sent. Now, the system hostname will be
set. Also, ifcfg-rh does not currently support this property, so there
is no way to disable this...)
Split a base NMSettingIPConfig class out of NMSettingIP4Config and
NMSettingIP6Config, and update things accordingly.
Further simplifications of now-redundant IPv4-vs-IPv6 code are
possible, and should happen in the future.
Merge NMIP4Address and NMIP6Address into NMIPAddress, and NMIP4Route
and NMIP6Route into NMIPRoute. The new types represent IP addresses as
strings, rather than in binary, and so are address-family agnostic.
The warning -Wstrict-prototypes was disabled by commit
db9b1df0e4 .
Enable it again, but avoid warnings for WiMax SDK by explicitly disabling the
compiler warning where needed.
Apparently clang does not produce a warning for -Wstrict-prototypes,
hence we don't need a clang specific #pragma.

nm_setting_verify() took a GSList of other NMSettings, but really it
would just be simpler all around to pass the NMConnection instead...
This means that several formerly NMSetting-branded functions that
operated on lists-of-settings now get replaced with
NMConnection-branded functions instead.
Add nm-core-types.h, typedefing all of the GObject types in
libnm-core; this is needed so that nm-setting.h can reference
NMConnection in addition to nm-connection.h referencing NMSetting.
Removing the cross-includes from the various headers causes lots of
fallout elsewhere. (In particular, nm-utils.h used to include
nm-connection.h, which included every setting header, so any file that
included nm-utils.h automatically got most of the rest of libnm-core
without needing to pay attention to specifics.) Fix this up by
including nm-core-internal.h from those files that are now missing
includes.
Code outside of libnm-core/ should not include the private headers.
nm-core-internal.h should be used instead.

This can be triggered by stopping the DBUS service. The assertion happens
because when the supplicant stops (due to the name-owner-change, which is triggered
because dbus-daemon quit), the supplicant manager sets all supplicant interfaces
to DOWN state so that they can be cleaned up. That does two things:
1) calls supplicant_interface_acquire() to attempt to re-launch wpa_supplicant
in case wpa_supplicant segfaulted
2) moves the NMDevicWifi to UNAVAILABLE state because the supplicant is gone,
the device is no longer usable and we must terminate the connection and wait
for the supplicant to come back
But #2 also ends up calling supplicant_interface_acquire(), because that's what
we want to do when the NMDeviceWifi is first managed (at startup) and when the
supplicant dies. The code just doesn't differentiate between the two cases.
To fix this, just allow duplicate "waiting for supplicant" pending
actions, which is fine because the operation doesn't care about strict
added/removed sequencing.
